The FIDO U2F Security Key by Yubico is a specially designed YubiKey, relying on high-security, public-key cryptography. Just  insert it into any USB port, and it works with any website that supports the FIDO U2F protocol, such as Facebook, Google’s Gmail, Google Cloud and G Suite, GitHub, Dropbox, and Dashlane. And all it takes is a simple touch of a button!


Two-factor authentication (2FA)  adds an extra layer of security to your account that you, and only you, can access in order to prove your identity.

Millions of people use YubiKeys fbecause they’re the easiest to use, super secure, and affordable. Plug in your YubiKey and tap it to log in to your computers, networks, and online services. Keep one on your keychain with the key to your house/car, and a second YubiKey in a safe place as a backup.



Prevents unauthorized access by requiring the physical presence of the key to log in on that device


Crushproof and water-resistant, no batteries or moving parts

Easy to use

Plug it in and touch the gold button or edge; no codes to type or apps to install

The same YubiKey can be used with nearly unlimited services

Easily integrated with the most popular services

Use it with popular services like Facebook, Gmail, GitHub, Dropbox, Dashlane, LastPass, Salesforce, Duo, Docker, Centrify, and hundreds more. Configurable for computer login (Windows, Mac, Linux). Follow the instructions that each service provides to register your YubiKey.

Easy-to-use protection with powerful and secure technology

Each Security Key has an individualized secure chip which performs cryptographic functions triggered by a simple touch of the key. You never see the details, but behind the scenes FIDO U2F Security Key provides a unique public and private key pair for each application it protects. Only those keys can correctly complete the cryptographic challenge required for login.

The secure chip is of the same class as those used in SIM Cards, electronic passports, military electronic IDs and chip-and-pin credit cards. Like those devices, the chip is specially “hardened” so it’s extremely difficult to steal the secrets hidden inside. The secrets contained in the Security Key belong to the end-user exclusively and are never transferred, copied or stored by a service provider or any other application provider.

This is not a biometric device, instead it uses a capacitive sensor activated by the small bit of electricity the human body naturally produces.
